X. DOUBLE DAFFODILS. 
Culture Outdoors. Daffodils appear to greater advantage 
and succeed best when grown in partial shade. A position where 
they can be protected from the midday sun will not only prolong 
their season of bloom, but will help to retain the bright color of 
the red- and orange-cupped kinds. In borders, a spot where 
taller plants provide some shade should be chosen and if the 
bulbs have to contend with the roots of moderately vigorous 
perennials, they seem to thrive all the better. Owing to the 
varying sizes of different bulbs, it is inadvisable to give an average 
depth at which they should be planted. A safe and simple rule is 
to cover the bulbs one and a half times their own depth, measuring 
from the part near the top, where the bulbs begin to swell into 
ovoid form, to the base. In light soils the bulbs should be set 
half an inch deeper. The distance between bulbs should be 3 to 4 
inches for the smaller sorts, and 5 to 6 inches for the larger ones. 
Never use stable manure unless it be thoroughly well rotted, and 
always keep it deep enough not to come in contact with the bulbs. 
Bone meal is as good a fertilizer as any. 
The Naturalizing of Daffodils in grass is a practice to be 
recommended, provided the attempt is made with the under¬ 
standing that success does not always follow. Certain soils and 
situations seem unsuited to this style of cultivation, and the 
beginner should be prepared to waste time and bulbs until the 
right conditions, and the best varieties for the purpose, are 
discovered. 
When grown thus, in meadow, orchard or lawn, a position 
should be given where the foliage can be retained until it has 
ripened. The turf should be lifted back with a spade, or with a 
planter made for the purpose, the soil slightly loosened and 
enriched with a sprinkling of bone meal and wood-ashes, and 
after the bulbs have been placed in position, the sod should be 
laid back and made as firm as possible. Planting must be done 
when the ground is moist but not sticky. Light soils usually 
produce the best results. Smaller flowers and slower increase 
are to be expected from this method of growing Daffodils. 
If the bulbs are dropped from the hand and planted as they 
lie, the natural effect of broad clumps will be enhanced. It is
